Best cleaner for bright seats

My car has (unfortunately) bright cloth seats. To clean, I had a lot of expensive products and also used. In a car repair shop, I came across the product of Fertan. It cleans my opinion the best. I carry the agent, let it soak in and then rub it (bought somewhere, kind Tupperparty? By my wife) with a damp cloth so the result is very good, so have bought even more sprays. Should now be sufficient in the coming years.
